Demigod System: The gods want to make me a saint but I'm a scum!

"I think I'd rather destroy the world than save it!" (The gods will pay you in gold!) "Maybe I might save the world afterall." Justin, having his every action controlled by a system he was unwillingly paired with, lived life much easier than he used to, excluding all the unnecessary attention and fame. He was known as the scum of the slums and daily necessities didn't come easy. He became the chosen one, the hero and all other adoring names all of a sudden and was being controlled by the gods to rid the world of the impending evil and train him in order to be able to go against Chaos. The evil god of disaster. The gods held Justin's past a secret and did not disclose to him that this was his second life. His first life... He was a disaster to all living things, including the gods themselves
